What's the name of this Master Of Disguise toy from the 70's?

OK, this is pretty pointless, but that’s the forum I guess.
Driving me nuts. Back in the late 70’s there was this bald doll/puppet thing that you could add various facial features, IE: scars, eye patch and a variety of hair pieces/ facial hair.

He was marketed as some sort of Master Of Disguise or something and was fairly popular, if memory serves.
Anyone remember what that little bald head’s name was?

HUGO! I remember that thing…creepy as hell.

Here’s a link.
